Respect the OS certificate store

[qc00]

Describe the bug
The "GitHub Actions language server" doesn't use Root certificates installed on Windows, so incompatible with an SSL-inspecting firewall.

Most other extensions in VSCode work just fine and are able to access HTTPS endpoints correctly. I presume they use a different API.

To Reproduce

1. Be in an enterprise environment with an SSL-inspecting/MITM firewall that uses certificates issued by an internal CA.
2. Open any workflow yml file
3. In the ouptuts:

}

Expected behavior
Certificates trusted by Windows are accepted.

Extension Version
v0.25.2

Additional context
I wonder if it's HSTS?

I'm having the same exact issue on my corporate device. We are behind the ZScaler proxy. Using the win-ca extension did not work as a workaround.

Can confirm this issue is also present on Mac.

To be more specific, it's only the language server that is not using it on Mac, the sidebar is working and showing workflow runs.

Same behavior on Windows. At least it's consistent.

Same here, Windows VSCode, the GitHub Copilot extension logs in fine after installing the win-ca, but this extension did not!
